1)SANDMAYER REACTION:-

The DIAZONIUM (C6H5N2Cl) is prepared by treating ice cold solution of ANILINE
(C6H5NH2) in excess of dilute HCl with an aqueous solution of NaNO2 at low
temperature (0-5)°C and the reaction is known as DIAZOTIZATION REACTION.
BROMO and CHLORO ALKANES can be prepared by treating a freshly prepared
DIAZONIUM SALT with CUPPEROUS BROMIDE or CUPPEROUS CHLORIDE and
this reaction is called as SANDMEYER REACTION.

2)GATTERMANS REACTION:-

This Reaction is same as SANDMEYER REACTION. But the only difference
between both of them is that here we use COPPER POWDER (Cu) in the presence
of HCl/HBr, and in SANDMEYER REACTION we use Cu2Cl2/Cu2Br2 as catalyst.

3):-BALZ SCHIMANN REACTION:-

It is a method of preparation of FLOUROBENZENE. In this method DIAZONIUM
SALT is reacted with FLOUROBORIC ACID, followed by heating the complex
compound formed.

4)FLANKLISTIN REACTION:-

AlkYL IODIDE (R-I) are often prepared by the Reaction of ALKYL CHLORIDE (R-
Cl) or ALKYL BROMIDE (R-Br) with SODIUM IODIDE (NaI) in Dry Acetone.
